We have established a comprehensive quality control system, covering chemical composition, mechanical properties, metallographic microstructure, hardness, ultrasonic testing and CMM inspection, ensuring full-process quality assurance from raw materials to finished products, and guaranteeing products at an industry-leading level.
Spectral Testing
Chemical Composition Verification
Accurate material identification starts with precise chemical analysis.
Using advanced optical emission spectroscopy equipment, NSPM verifies the chemical composition of every steel grade to ensure compliance with international standards and customer specifications.
This process guarantees material authenticity, alloy consistency, and stable performance throughout the entire production cycle.
Ultrasonic Testing
Internal Quality Control
Detecting what cannot be seen.
Advanced ultrasonic testing technology is applied to identify internal defects such as cracks, inclusions, and discontinuities hidden beneath the steel surface.
Through strict non-destructive inspection, NSPM ensures superior internal quality and reliability for demanding applications including molds, tooling, and precision components.
Hardness Testing
Consistent Mechanical Properties
Uniform hardness is essential for stable performance.
NSPM performs hardness testing throughout the manufacturing process to ensure consistent mechanical properties across different sections of the material.
This helps customers achieve predictable machining results, extended tool life, and reliable performance under demanding working conditions.
Metallographic Microstructure Analysis
Microstructure Evaluation
Performance begins at the microscopic level.
Through metallographic examination, NSPM analyzes the internal microstructure of steel, including grain structure, carbide distribution, and heat treatment quality.
This microscopic evaluation ensures optimized material performance, toughness, and resistance against fatigue during real-world applications.
CMM Inspection
Precision Dimension Verification
Precision is measured, not assumed.
NSPM utilizes Coordinate Measuring Machines (CMM) to verify dimensional accuracy and machining precision of customized steel components.
With advanced measurement technology, we ensure strict tolerance control and reliable integration into customers’ manufacturing processes.
Mechanical Performance Testing
Real Performance Validation
Beyond specifications — proven performance.
NSPM conducts mechanical performance testing to evaluate strength, toughness, and durability under practical working conditions.
These tests provide comprehensive data support and ensure our steel products deliver dependable performance in critical applications.
